Beautiful Games: frozen waterfall climbing

These remarkable photos of professional ice-climbers tackling huge frozen waterfalls and icefalls in Eidfjord, Norway, were created by photographer
Thomas Senf. He used spotlights and flares to illuminate the spectacular landscapes at night-time, achieving results which look other-worldly. It took several hours to prepare for each shot – each light had to be fixed into the ice and 500 meters of cable was needed to rig everything up – with the help of Mammut alpine equipment. The falls themselves are up to 500m high. Senf's photography includes rock climbing, ice-climbing, mountaineering, skiing and base jumping. He is himself an accomplished mountaineer, having made first ascents of two peaks in the Garhwal Himalaya
